Seperating color

One way that light creates color is by passing through things. During the day the sun's light passing through the sky is perceived as blue, but at sunrise and sunset the color changes. When the sun is that close to the horizon, the light passes through the atmosphere, dispersing the light. Colors of red and orange are often seen.

A similar effect occurs when light passes through a prism or water. Instead of a solid color appearing however, the light separates into seven colors; red, orange, yellow, green, blue, indigo, and violet. The separation of the colors is sometimes more prevalent than other times.
